A Review Paper On Microstrip Patch Antenna

Abstract

Dual or multiband antenna has been playing a crucial role for communication in this rapidly evolving wireless communication world. Antennas are based on transmission or reception of electromagnetic waves. Microstrip antennas
have several advantages over conventional microwave antennas and is widely used in various wireless communication systems due to its compact
size, low profile, and ease of integration with other
electronic components. It consists of a thin metallic
patch, typically made of copper, mounted on a
dielectric substrate, which is usually a thin layer of
fiberglass or ceramic material. The patch is fed by
a coaxial cable or a microstrip transmission line,
which is connected to a feeding point on the patch.
The radiation pattern of the antenna is determined
by the shape and dimensions of the patch, as well
as the substrate material and thickness. Microstrip
patch antennas can be designed to operate at
different frequencies, and can be used for various
applications such as in mobile phones, wireless
routers, and satellite communication systems. This
paper presents a review of Microstrip antennas
with different feeding techniques
